摘　　要：本文在探讨该矿点的蚀变类型及蚀变特征的基础上,通过对森吉银钼多金属矿点和哈喇图钼矿的蚀变特征的对比,从蚀变岩石的野外和镜下特征来来分析了蚀变与银钼矿化的关系,认为森吉银钼多金属矿点存在类似于哈喇图钼矿的成矿特点。蚀变特征对指导找矿具有初探性的意义,希望从这个突破口来指导找矿。其中野外明显的硅化和镜下强烈的绢云母化可能直接指示银钼多金属矿的形成,推测该矿点可能是典型的斑岩型银钼多金属矿床。This article was to explore the mine point of alteration type and alteration features,on the basis of through senjiAg-Mo polymetallic point and clams contrast figure of molybdenum alteration characteristics,from the field and the microscopic characteristics of altered rocks to analysis the relationship between molybdenum mineralization alteration and silver,thinks that there are similar to senjiAg-Mo polymetallic point halatu molybdenum mineralization characteristics.The alteration characteristics are of primary significance to guide prospecting,and it is hoped to guide prospecting from this breakthrough point.The obvious silicification in the field and strong sericitization under the microscope may indicate the formation of Ag-Mo polymetallic deposit directly,and it is speculated that the deposit may be a typical porphyry Ag-Mo polymetallic deposit.
